6.6. Downlink hierarchical QoS scheduling configuration
The OLT three-layer QoS scheduling is only for ONU downlink service, for uplink service support only
8 queue scheduling of unicast in a single ONU, for each ONU to provide up to 8 queues used to
distinguish the services (Note:
the supported queue number is related with the ONU registration
profile, refer to "the ONU type profile configuration" for details), each ONU can use different
scheduling policy; OLT support WRR (weighted round robin) scheduling between the ONUs in one
PON port; for all the unicast and multicast service a single PON port, OLT strictly follow the principle
that multicast service has higher scheduling priority, to guarantee the multicast service.
6.6.1. PON port configuration
Set the PON1 port scheduling mode as hierarchical scheduling configuration.
OLT (config) # interface gpon-olt 1/1
OLT (config-gpon-olt1 / 1) # qos-queue-scheduler model hierarchy
Note
：
After modifying the QoS scheduling profile, OLT needs to be restarted.
Modify the scheduling to hierarchical mode, the configuration such as rate limit, uplink port cos-
queue will not take effect and need to be reconfigured, in which qos-queue-scheduler, qos-queue-
traffic will not be configurable under hierarchical mode.
6.6.2. ONU Configuration
Configure ONU downlink bandwidth
OLT (config-gpon-onu1 / 1: 1) # qos-onu-bandwidth min 100 max 1000
Note
：
The maximum bandwidth configuration of the ONU must be no less than its minimum value. If the
maximum or minimum configuration is 0, the maximum / minimum bandwidth of the ONU will not
be limited. There will be no downlink rate limit for ONU by default.
View the ONU downlink bandwidth configuration:
OLT (config) # show qos-onu-bandwidth interface gpon-onu1 / 1: 1
qos-queue-bandwidth min 100 max 1000
Configure ONU weight
OLT (config-gpon-onu1 / 1: 1) # qos-onu-weight 1
View ONU weight:
OLT (config) # show qos-onu-weight interface gpon-onu1 / 1: 1
qos-onu-weight 1
